A gyro plate with two sides is 250 pesos and a gyro sandwich alone is 150 pesos. A gyro with fries or only one side is 200 pesos. Coca Cola is about 50 pesos if I remember correctly.
If your going with a couple people who like a taco or burrito you can easily split up and order your food separately and share a table. Both restaurants are located next to each other and share outdoor seating or have indoor air conditioned seating.
