Best of Delray and Vicinity?
A few very recent well populated threads should give you some more ideas, as well as post-visit followup from recent diners...
Food obsessed New Yorkers seeking recs for Boynton,Delray, and around:
Lunch in Delray
Sophisticated, Chow-Worthy Spot - Delray to Boynton
Date night in Delray?
Burger-Fi and Ellie's Diner in Delray are both casual, fabulous options. And both have incredible milkshakes. There's also a hidden gem by a movie theater in Delray called Kabob House, I believe. Very good, very authentic Turkish food. Place doesn't look like much but is absolutely dynamite and always our first dining stop whenever we visit. If you have time, you should consider visiting the Morikami Japanese Gardens and Museum and grab lunch in their restaurant. Beautiful and yummy.
Chez Jean Pierre in Palm Beach is great. Buccan, also, in Palm Beach is very creative. 32 East in Delray is very good with a great wine list. Tramonte is in Delray is an offshoot of Angelo's of Mulberry Street. Max's Harvest in Delray is farm to table. If you want steak, NY Prime in Boca is excellent.
I've not yet been to The Grove so I can't fairly comment on the food. I have heard mostly - but not exclusively - excellent things about it.
I can say the atmosphere / experience will be quite different.
Max's you're looking at fairly loud, high-energy with bar for 8 and maybe seating for 75 or more across multiple rooms, and an extensive menu. http://www.maxsharvest.com/menu_food.html
The Grove is much more intimate, with a small staff, a small room, and a very small menu - typically 4 or 5 apps and 4 or 5 entrees (I know this much because I have walked past many times and checked the nightly menu). Here's one, possibly old:
So FWIW there's a bit more info, if that helps at all.
