One great thing about Main Street St. Charles is that it's full of family owned, non-chain, unique restaurants. While the upside of this is a friendly and casual environment with original dishes, the downside is often inconsistent food and more often limited menus. Quintessential is the exception, with a vast menu and more upscale preparation than most on Main Street,... More

The Q is a place where you will find folks enjoying a time dining early in the evening and "kickin' it" later in the evening. The food is inviting, the spacious bar area, live music, outdoor seating area with fire pits will keep you entertained into the night.

Great place wiht a no smoking downstairs. Wonderful service and the food is the best in St. Charles. Nice variety and always tasty.

My first trip to Quintessential was this evening and I was very impressed. The restaurant has more of a darkly lit, romantic and hip vibe.

We ate on the rooftop deck. Very friendly staff, great variety of food, excellent tasting food, and musical entertainment. Great ambiance!

The atmosphere inside this place is amazing, the upstairs deck is fabulous and the food is great. However, the service is not great. Having eaten here a handful of times I always assume that I had a crabby hostess or waiter. I think they are just all "a little too good for small town St. Charles folk" The staff seem... More
