Took a recent 'hound recommendation to try the Lost Dog Cafe in Arlington for a Sunday-afternoon casual afternoon, and I was impressed by the menu and the variety of beers, and I would have loved it (thanks for the suggestion) BUT...
1 - The entire population of Arlington was trying to get in 2:30 Sun afternoon (don't these people have anywhere else they need to be?) and I was asked to wait over here ... no, I'm not in the deli line ... over there ... yes, I'll move so you can get a T-shirt ... over there ... yes, of course, come right on by.
2 - Booths. Lots of booths. Maybe a table or two. And the booths were designed for the great majority of the clientele: little 20-something slip-of-a-things with no waistlines and their boyfriends, also with no waistlines. I admit, I'm a VERY sizeable person, but I literally could not fit into the booth - I tried, like a fool, and had to be helped out.
No food report - we didn't stay. I spent the rest of the day sulking because I don't often encounter the "someone your age and size just doesn't belong here" problem. Not from the staff, they were very sweet, but running into the brick wall of reality is not my favorite occurrence.
Anyway, give the place a try, but measure your waistline first.
