We decided to try our luck and walked into Jules on a Saturday night around 6:00 without reservations. There was only one other couple dining at the time so it wasn't busy at all. This location looks a lot nicer than the one on Spadina and was a great date night pick. The hostess told us there would be another party coming in at 7:30 and we agreed that we could finish our meals by that time. I originally wanted the cote de boeuf (which was priced higher on the physical menu than on the online menu) but decided on the prix-fixe at ~$29/person.
To start, we got the french onion soup and caesar salad. I thought the soup was way too salty but otherwise, not bad. The salad had a nice tartness and tasted fresh. Our entrees were the steak frites and chicken with mushroom/ cream sauce. While the steak was very thin, the medium-rare cook on it was good and the end result wasn't chewy. The sauce for the chicken was delicious and I ended up dipping my fries into it too. I can see why a lot of reviews here say Jules' fries are similar to Mcdonalds but the former tastes a lot better! Our desserts of the chocolate mousse and creme brulee were nicely executed but nothing special.
Overall, I'd give the food 3 stars but the fast service makes it a 4-star meal. Everything we had was good and simple but I did want a little bit more to each dish. Still, I'd definitely return to have the prix-fixe again - its such great value.
