First time there and it was really nice ! The price range is totally reasonnable! For 1 bacon cheeseburger, 1 cheeseburger, 1 small fries (way enough for 2) and 2 drinks we paid 17$ almost the same as McDonald. Food wise the experience was very positive. Bacon was crispy, meat tender and not too cooked and we could customize our burger. The fries are delicious, crispy and they arrived very warm.
At the end we were super full and I'll definitely come back to 5GB!
