Just a reminder to everyone that this year there is going to be a Taste of Georgetown. Sadly, it is the same day as Taste of Bethesda, but the good news is it goes for another 2 hours than Taste of Bethesda. My recommendation....Go to Taste of Bethesda at 11. Eat a ton of food, but not TOO much. Rest for a while at Rock Bottom Brewery and have a few beers. around 2:30 or 3, hop on the Metro and take it to the Tenleytown metro. Then get off and hop on one of the 30 buses out front of Best Buy to Georgetown. That will give you a few hours to sample all the food there as well. Of course, you could always do the reverse as well. This is the link for the full details of the event.
OK, so you might not have to do the whole runaround like I said above because according to the Washingtonian, Taste of Georgetown is not until the weekend after Taste of Bethesda. It actually will be "11 AM to 6 PM on Wisconsin Avenue between M and South Streets, NW, and on the grounds of the Grace Episcopal Church" as quoted from the Washingtonian web site.
