I used to go to the Little Sheep in Montreal all the time, and I decided to give this one a try. To my surprise it was a lot better and there seemed to be far more selection than the one in Montreal. The servers are about the same and only come by your table when you wave them down. That's to be expected though as this place gets super busy. Don't even bother coming with a group without making a reservation, as the wait times are very long. Even with a reservation our group still had to wait in excess of 20-30 minutes on a weekend.
The food here is typical with your meats, veggies and select sea food. The lamb and beef which is not self serve are usually fresh and taste great. The meat on the shelves though, are usually a bit more rough looking, and sometimes the trays need to be cleaned a bit more as I've seen some funky cross contamination happening in many of the food trays.
Overall for the price and value you can't really compare with anything else in the GTA. This place is busy for a reason, it offers great value with nice food and the call you can drink area is a nice touch. Try mixing the orange pop with coke, you won't regret it!
