We have a group of 23 staying in Lenox, MA the first weekend of May and need two restaurants for dinner.

Looking for nice, but not formal or real upscale dining. Price is a factor for some. Also have people who are vegan and gluten free.

The following look good to me:
Morgan House Inn, Lenox
Sullivans Station, Lee
Sloanes Tavern, Lenox in the Cranwell Resort

Has anyone been to any of those or have better suggestions? Thanks.

I haven't been to any of those, sorry.
Check out Elizabeth's in Pittsfield ( you might need the whole place) . I would also consider Enzo which is Asian but has a very large and very varied menu.

I cannot recommend Sloanes. I do stay at Cranwell once or twice a year for a weekend getaway and love the property, but the tavern is nothing to write home about.

Eat on North might be a possibility.

I've removed Sloanes from the mix.

Anyone familiar with Salmon Run Fishhouse in Lee? I'm surprised that there don't seem to be tons of good restaurants in the area.

My favorite place to eat in Lenox is Zinc and second favorite is Prime.
Pairie Whale in Great Barrington and there is a thai place in GB that is the best I've ever had but I can't remember the name.

Also, in West Stockbridge there is Rouge is excellent and the Vietnamese place in West Stockbridge is large and fantastic as well.

The places you've mentioned just never interested me, except I have had Thanksgiving dinner at the Cranwell and it was excellent.
Have Fun in the Berkshires.

That's an awful lot of people. There are tons of good restaurants -- stowed lake mentions two in West Stockbridge alone -- but the ones I like a lot are unlikely to fulfill all your criteria (big, vegan choices, moderate prices).
