Clio is located at the corner of Comm Ave and Mass Ave in the Elliot Hotel. The restaurant is a nice space overlooking Mass Ave - spacious, but intimate feeling (probably because it was correctly lit for a romantic dinner.) Amy and I went with two other couples - we'd already had a snack at Figs so we weren't starving when we were seated at 8pm. We ended up with a 3 hour meal that was lovely - I started with the beet salad (awesome) and had a mescaline salad for my main course (see - I wasn't really hungry). Amy had the yellow tail tuna app and the lobster with ginger carrot puree. She loved it and managed to snarf it all down even after the Figs fig pizza extravaganza.
We had a wonderful evening with our friends, who also thoroughly enjoyed their meals. The only bummer is that the bathroom is through the hotel, down stairs, and around a corner, so the "short visits" to empty the tank after all the bottled water took a little longer than usual.
