They are always busy in the mornings (hospital and school employees work nearby) but are much quieter later on. Parking is usually good and definitely better than nearby coffee shops.
Make sure you know what you're being charged. I'm overcharged almost every time for the same beverage (anywhere from 50 - 75 cents, depending on who's at the register)
Friendly staff. I'm here some mornings after dropping off my hubby & hang out on a comfy chair near the entrance w/my netbook! If you'll be sticking around, ask to have your coffee served in a mug.
