While it wouldn't be at the top of my list, we ended up at the Irish Inn at Glen Echo on Saturday night, due to my food persnickety parents.
The building itself is nice and has been renovated well in an Irish country cottage kinda way - a medium sized room dowstairs and several several smaller rooms upstairs.
Our waiter was a total chump/bozo and basically lost us at hello. There when we didn't want him, not there when we did, blatantly tried to upsell us on our wine order (when I order a $36 wine I don't want to be told the one I should really get is a $65 one), and provided blustery answers to a few simple inquiries about the menu.
Apart from all that the food was actually decent. Wifey and dad had a smoked salmon and lobster gnocchi dish which tasted good, I had mussels. Three ordered steaks for entrees which were also decent, and I had shrimp and scallops w/ chorizo sausage w/ tomato grits - good, but maybe an overabundance of flavors.
For dessert we split 2 apple crisps, which my Dad who adores apple pies/crisps of every description declared to be the best apple dessert he'd ever had in the States (I thought it was good but not that good).
Total bill incl tax, tip and wine approx $220 w/ a $15 off coupon we found somewhere. Personally I'd rather to go Bucks any day over this - it wasn't terrible but for the prices we were paying I expected more.
