At this point you can increase your prices a bit. You have made your name and everyone knows just how good the food is. There is no need for you to work off of razor thin margins anymore. People will pay more for quality and consistency.
Any customers you may lose due to the price increase will allow you to still have product into the later hours. This is how you dont have to increase capacity, make more money and not run out of food so early. And if you have outgrown this place any bigger place will eat into those razor thin margins. My suggestion is to increase the prices to where you are making an honest profit and see how it goes. If the summer is going to bring that much of an increase of people I dont think you will suffer any. Tourists generally expect to pay more and if they pay more for high quality it will be a bargain for them.
