Suggested Tavern Layout

Just a small guide suggesting an aesthetically and well laid out tavern. It provides plenty of room for guests and workers and has centrally located Cleaning rooms and Clinics. It also positions Dormitories and Quest rooms together and separates them from the rest of the tavern where it is easier to locate what is going on. It also keeps customers on the left and bottom of the Tavern and away from Dorms, Clinics, Cleaning, Quest, and other rooms. When I first started, I built rooms as needed and soon lost track of everything. This centralized layout really helped and will also allow you to make plenty of money. Profit varies, but I generally make over 200k an hour and often more with this layout.

Tavern Layout

Each area is clearly marked with a different color. There are 10 rows by 13 (single room) columns. I used Excel to design the room layout diagram.

-
Originally I had seven Cleaning rooms and six Quest rooms and 12 double Dormitories and one single Dorm, but realized I didn't need that many Cleaning and Quest rooms. So I made more room for two more double Dormitories. I was also losing money, and realized it was because I had upgraded all the Dorms to rank 2. So, originally the Clinics, Dorms, and Quest rooms were aligned up and down horizontally, giving one space for a single Dormitory next to the Training rooms. There was also one extra single Massage room where the offset Clinic is now located.

Either design works, but the original, as shown in the below layout, costs more and provides less space for girls and wasn't quite as efficient.

Dormitories
The double room Dormitories are all at rank one since they're only 300 gold maintenance fee. At rank two, for just two more slots, each room costs 4.5k gold maintenance fee. That cost really adds up fast and eats into your profit. With five Quest rooms, I do use most of the 15 available quest slots, 13 to 14 out of the available 15. I have 10 girls questing for normal ingredients and keep 3 quest girls in reserve for special ingredients and crafting ore. I also keep one girl for one time quest ingredients to satisfy those "visitors". (The shop never seems to have the one or two ingredients you need when the quest giver wants it.) My idea for Dormitories and Quest rooms was to have them separated from everywhere else. It works out okay, especially aesthetically, but not quite as I envisioned as you can't choose which girl stays in which dormitory so they still have to go up and down the stairs to reach the quest rooms as needed. Current layout gives room for 64 guests and 56 girls. The right side Training room will eventually be a Dormitory for a total of 60 possible girls. I'm currently only missing Calypso and have Many dupes. So the current layout gives plenty of room for all available girls with a good many dupes. (I have no two star girls.)

Note that one Double Dormitory or Two Single Dorms provide the exact same amount of space and cost the same for maintenance as well.

Storage Rooms
All Storage rooms are max rank (and so are all other rooms, except Dorms). I found that if you keep up with questing and cooking, you only need four double storage rooms. You could use more, but you'd earn less profit and have less room for guests and girls. (Four double or eight single storage rooms cost the same maintenance and hold the exact same amount of ingredients.)

Onsens and Saunas
I have four of each bathing rooms, Onsen and Sauna. That seems to work out okay. Having four of each gives some profit sources other than Dining and Massages. It took a good while to obtain and train and rank up the massage girls I have to fill all the rooms, not to mention provide all the items to give them tip bonuses. I intended to have two rows of Massage rooms above the Dining Rooms, but ended up just filling in all other spaces I didn't use for something else, with massage rooms. And as you can see from the pics, they're all being used.

Clinics
I felt that four Clinics were necessary. When I was training, re-rolling, and starring up, and had four training rooms, instead of just two, there were only three Clinics. (You can see the one Clinic and one Dormitory space I was using as Training room spaces.) I found that some girls were getting sick and had to wait to be seen, not often, but it did happen. So having four Clinics, seems to be ideal and most efficient, at least for my layout with 55 girls so far. I don't plan to have more than 60 total girls.

Guest Rooms
The Guest rooms are mainly on the first and second floors and near the stairs to give access to the Massage rooms and Onsens, Saunas, and Massage rooms and keep guests from walking through Clinics, Cleaning Rooms, Training Rooms, Quest Rooms, Storage Rooms and Dormitories. It cuts way down on confusion with so many people walking around at once.

Cleaning Rooms
Cleaning rooms are mostly centrally located and are all single rooms. My idea was to have Cleaning rooms on most floors so the cleaning girls wouldn't have to walk as far and thus make cleaning quicker and more efficient. I wanted cleaning rooms on the first floor as well, but just didn't have room. Only Dining Rooms, Massage Rooms, Onsens, and Saunas need cleaning, so I wanted the Cleaning rooms as near those as possible but also out of the way of everything else. I might could get by with less cleaning rooms, but some redundancy means the money making rooms always get cleaned even when some cleaners are at the Clinic. (The higher starred girls also have voice lines for cleaning, so you get to hear those as well. Some are pretty humorous.)

Dining Rooms
Six Dining rooms seemed ideal. I could have lined them up horizontally somehow, but I always envisioned two rows of Dining rooms on the bottom. As you play, you'll learn recipes that use 1 of each ingredient instead of two, each utilizing one of the special ingredients, eyeball, heart, and dragon fruit. Using those 3 recipes and the ones with just two ingredients, one with fish and one with clams, seems to be enough to feed six dining rooms worth and utilize four storage rooms efficiently. I still run out of storage room even when all five dishes are on auto cook. It also takes 13 out of the 15 available quest spots you have and keeps five orders going at once. The two dinners shown that have only two ingredients sell for only around 1k and 1.2k gold each. But gathering ingredients for these two dinners helps not to overload your storage rooms, too fast, and keeps ingredients needed to a minimum for five dinners on auto cook. Each of the special dinners sell for 3.5k gold each so it all evens out. The other double ingredient or single ingredient dinners are worth very little and should be abandoned after you learn the special quest reward recipes.

Blacksmith and Shop
The Blacksmith room and Shop just need to exist and so I put them as out of the way as possible. The Shop is on top of the check-in room and the Blacksmith is on the very top on the left hand side, as out of the way as it could possibly be. Please don't build more then one Blacksmith!

I hope some of this info helps and is written clearly enough to understand easily. Maybe someone can even use this layout as a guide and make an even better one.

Here's actual in-game screenshots of the layout of my tavern. It's so big at full size, I had to take two separate screenshots, even zoomed out all the way.
