A short take on my second visit to Avec (but first time eating there):
The housemade sausage was the best. Very nice - a must-try dish.
The dates wrapped in bacon were also great - what a nice combination of sweet, sticky fruit and crisp, salty bacon.
The beet salad was another winner. It was served on slabs of a mild cheese - either farmers' cheese or mozarella - which was a nice textural combination.
The mussels were the only disappointment. They were small and tasted "off," and the housemade chorizo that was supposed to be part of the dish was hardly to be seen or tasted.
Little freshly baked loaves of bread are served with each round of small plates. These were very good and rich with olive oil (ciabatta or focaccia - I'm not sure which).
Desserts are not the focus. There were no pastries at all -- just sorbets, gelatos and custardy things. The blueberries topped with egg custard were nice, but the chocolate mousse was nothing special.
The wine list is immense, with many offerings in the 250 ml size (two glasses). I stuck with gin and tonic - they didn't have Hendricks, but they did offer Miller's, which was nice and smooth.
The space itself has been much-reviled by reviewers (it's narrow, sauna-like, noisy, crowded with the communal seating, uncomfortable with the backless hardwood chairs). This is all true. Seems like it might be best to go either very early or very late to avoid having to shout in order to converse. I also found the service to be slow and lackadasical this time, which was not true of my first visit.
