I love Mellow Moods. We frequent Shepherdstown several times a month, and Mellow Moods is usually where I want to eat lunch.
The Baja Fish Tacos are to die for! As is the Thai coconut hand pressed soda. We like to eat outside when possible and they are a great little seating area out back. It is quaint and the staff is always friendly and helpful. They accept credit cards, but if you can bring cash, please do so.
