I go to Essence fairly regularly, and lament often at the fact that it's a breakfast/lunch place and I can only go there on Saturdays!
Essence is a cozy little cafe hanging out across the parking lot from a Starbucks. Step inside and there's usually a line at the register, most of the tables are usually full. Both signs of a good eatery. It smells like pastry right when you walk in, the buttery scent of croissants makes your mouth water. All of the pastries I've had have been wonderful. Most especially their macarons. Classic French sandwich style cookies with creamy filling are a must-have whenever I stop in. They have a wide range of flavors that tend to change seasonally and also week to week, some of the regulars include Caramel, Hazelnut, French Chocolate, Espresso, and Chocolate Mint. Seasonally they have Strawberries and Cream and Pumpkin. Their croissants are absolutely delicious and a great little breakfast on their own.
Grab a vanilla bean iced coffee and one of their Big Breakfast plates and you will not be disappointed. The coffee is smooth and sweet, and they mean big when they say Big Breakfast. Local made sausage, potato cake, fried eggs, and house made bread and jam all work to satisfy even a picky eater. Other delicious menu items include a Croque Madam with tomato, ham, and cheese, hot cereal served with yogurt and fresh fruit, quiche lorraine served with either fruit or a side salad. All worth a first trip as well as many more.
I've only had lunch here once or twice. I was less than thrilled with a mozzarella and tomato grilled sandwich, but I had a burger made with grass-fed beef that was divine.
They get most of their ingredients locally and it tends to be organic, which makes for pricey but great and good for you food. My biggest gripe with them is the wait when they are busy. You can wait up to 40 minutes to get your food, but that's when it's very busy, and I think it's worth the wait (as long as you don't gnaw your arm off in the mean time... but that's what pastries are for, right?).
