Without knowing your budget...
You mentioned breakfast-lunch-dinner for 4 days, all within walking distance. Keep in mind, while Buffalo is not really known for it's easy public transit system, you hotel is walking distance to the Main Street/Allen Street station of the light rail train that will take you south into downtown, or north to the University city campus. Either direction will open up a plethora of dining choices.
But, if you are walking just in the neighborhood, here is how I would structure it.
BREAKFAST AND LUNCH...
Towne Restaurant. Quintessential Greek diner. A Buffalo institution. Gyro, Soulvaki, Chicken with orzo. Save room for rice pudding. $
The Towne. Oops, I said that already...
Ok, How about...
Cafe 59. I havent been - but the wife has - and said it was good. Soup & Sandwich $
Quaker Bonnet. Sandwich Shop across from the Towne. $$
If your budget allows it - Tempo is very fine restaurant - and right across the street from your hotel. This is more of a "white linen" type of establishment, if you get my drift. Expect excellent service, top quality cuts of meat, flown-in seafood (raw oysters - yum), fabulous wine list, etc. My wife believes this is the best kept secret for Buffalo's best steak. You will not be disappointed. $$$
Right next door to Tempo is a tavern called Colter Bay. A very good selection of micro-beers, if beer is your thing. I have never heard anyone rave about the food. Expect passable pub grub. The beer, and sports on the screen, is the thing here. $
Mother's, on Virginia Place, an alley, off of Allen Street, from your hotel walk one block south to Allen turn left and look for Virginia alley on your right. Kind of hidden, but a huge local favorite - can get loud when busy. Nice selection of wine. $$
As a native Buffalonian, I feel obligated to recommend a fish fry if you are here on a Friday. For this Buffalo institution you will want to go to Ulrich's, the oldest continually running tavern in Buffalo. This is a German-Irish tavern that is "old-school", no faux-pseudo-insta-ambiance here. You can also get a good beef-on-weck, and german sausage platter here. Flying Bison, a local brewery is prominently featured here. Look for "Hoops" ale, available exclusively here. Or order the German-Irish "U-Boat," half-Guinness, half-Warsteiner. When Anthony Bourdain was in town shooting No Reservations, he visited Ulrich's. Look for the show to air in July. $
Gabriel's Gate. This is the place to go, within walking distance, for wings. Sandwiches are always good. Real wood-burning fireplace, too. Nice bar. $$
There will always be people that tell you to go to Anchor Bar, the originator of Buffalo wings. They are within walking distance, also. This is a good place to go if you are a tourist and want to go to a place with a lot of crap hanging on the walls. $$
Laughlin's, contemporary Bistro with very cool interior. Cajun fish sandwich is excellent. Flying Bison here, too. $$
Rue Franklin, indisputably Buffalo's finest French restaurant, open for dinner, intimate but unpretentious. $$
LATE NIGHT DRINKS
Sample. Sexy, sleek, small plates, tapas, cocktails, etc. $$
Allen Street Hardware. Feels European. Small, but quality wine and beer list. $$
Nietzsche's. Nitty gritty rock club. Local favorite. $

Your profile mentions you liked Dinosaur BBQ - you might like to try Kentucky Greg's BBQ while you're here. It's out in the burbs, so if you don't have a car, it wouldn't work.
Rue Franklin - closer to where you'll be staying, does French style fairly well.
Beyond that, as far as recommendations go, Jerry's right - we'll need more information. But do check out his link to Rapaport's site.
