I am running a similar concept bistro (sandwiches, salads, cheese courses, etc) and I will list the cons that I had found in the operation:
- When you do not have a server your check is going to be lower. We sell beers and wines too and people order at the register and the hospitality take the food to the tables. So it is annoying if you drink a beer and have to stand up from the table and walk to the register to order another one.
- You pay for hospitality at least $8 per hour and you are not giving a full serve, there are customers that would like to be serve at the table. The worst case is that hospitality employees are earning to low and is difficult to find and keep good people with skill in this position
- If you pay a waitress you can pay lower salary ($5) but they will earn more because of the tips, so you can hire better people and people that might offer you some stability. You are expending less in wages and salaries and getting a higher check average.
- If you want to offer pizza and the main concern is volume, you might be in the right path but then your price point will be too sensible.
