Having discovered this forum, and being a long time Olney resident... I offer my opinions. Roughly in order of my favorites...
Someone wrote that there were limited choices in Olney... not so, at least now.
All are within two blocks of Georgia and 108 unless otherwise noted.
Inn at Brookeville Farms... a couple miles north on Georgia Ave.
Olney's most credible attempt at a fine restaurant, continental, good wine list, 1/2 Price wine bottles on Mondays.
Bella Notte... good family Italian, cute and cozy, used to be a bargain but has gotten a bit pricey with entrees around $20.
Mannequin Pis... snooty Belgian, food really quite good, most expensive, the only beers are a huge selection of bottled Belgian which start around $7 and go way up. Specialty is mussels offered at least a dozen ways. Smallish, the only place where you probably need a reservation.
Al Sospiro... new small Italian restaurant, great fresh food but limited menu, usually a fresh fish special. $20ish+.
Olney tavern... really quite good food at $15 prices in a place that does not quite know if it's a bar or a restaurant... it's really both with two sides. Dogfish 60 minute IPA on draft... yum. Music on weekends. This may be our best combo of food and price.
Sol de Azteca... upscale Mexican with the usual menu plus some... duck dishes and pork morsels in bitter orange... recommended.
Mamma Lucia’s… crowded, noisy Italian. Pretty good food, big menu, $20+ prices kind of exceed the quality in my opinion.
Olney Ale House... a landmark with homey food and rustic hippy biker chic. A mile east of Olney on Rt. 108. Changed owners a few years ago and trying to become more of a restaurant... the prices have succeeded, the food not as much... but great beer selection, at least a dozen on draft and twice as many bottled,
Thai Cuisine... this small place used to be carry out only but added a half dozen tables... surprisingly good Thai food.
Sukura Palace... Benni Hanna formula Japanese steak house... group table around a grill with cook putting on a show... the food is good but the menu is limited and the ritual takes a while. $20+, Good for the experience on occasion.
Riccuti's... Upscale Italian with wood oven pizza. Pretty good but a bit pricier than the food deserves, $20+.
Wasabi Zen... Olney's sushi-ko... good sushi but not a lot else, teriyaki disappoints me. A bit pricey.
Olney Grille... this place is always crowded but I really don't know why... I guess the fresh fish is a strength, but I find it pretty mediocre.
Hunan Delight and China Harvest... our two Chinese restaurants are both bargains but undistinguished.
B. J. Pumpernicks... I wish we had a good deli, but BJ's does not make it in my opinion. Huge menu but I still haven't found much that I think is good.
Chains… McDonalds, Popeyes, KFC, Jerry’s, Quizno’s, Chicken Out, California Tortilla, Rita’s, Cold Stone, C’Burger C’Burger
