Sorry for not giving everyone more advanced notice about this, but Taste of Wheaton is today. I have no clue what restaurants are participating, but I plan to go anyway. I've been meaning to check out the new restaurants in the Wheaton area for a while now. It's going on today from 11 AM to 5 PM at Wheaton Triangle: Reedie Drive and Grandview, Wheaton, MD 20902. Tickets are $1 each and get you one taste of food per ticket.
Thanks to Wahoooob for the tip.
