CENTER CITY. If you plan to spend your day in Philly beating the pavement and bopping into and out of the shops around Rittenhouse Square, do your constitution a favor and also plan to stop a few minutes at the Radisson's Capriccio's Coffee Bar. Here, in addition to cappuccinos, lattes and espressos, they also serve up some rather tasty munchables, including several different types of pastries and sandwiches.

OLD CITY. This comfortable little shop is a great place to "fuel up" in the AM if you plan to tackle the popular Constitutional Walking Tour. Aside from all your favorite coffee drinks (good energizers, to be sure), Caramel also has some dandy, homemade tide-me-overs like Belgian chocolate bars, cookies and candies. In the afternoon, the menu changes a bit, offering terrific panini, specialty sandwiches, salads and soups. And while those are all tasty in their own right, you'd be remiss if you didn't leave room for a bit of dessert sampling ­ perhaps a tartlet or a slice of tiramisu (just $5).

SOUTH PHILLY. Do a few things and do them well. Carman obviously believes in this philosophy ­ the menu, which features five or six dishes, changes daily and is recited by your server. Quirky combinations and breakfast standbys with a twist are the norm; loyal patrons swing by regularly to sample Carman's old favorites and new concoctions. Call ahead to reserve a table ­ the place is small, and it gets packed. After visiting once or twice, Carman will probably call you by name.

CENTER CITY. Located in the Four Seasons Hotel, the Fountain sits in the middle of one of the most visually stunning settings in the city. Diners may opt for th eprix fixe menu, or choose from the a la carte selections. New American cuisine, with an emphasis on fresh seafood, is served at this refined and elegant establishment. Truly a special occasion destination. Fountain also delivers an oustanding Sunday brunch ­ one that features roasted monk fish osso bucco and grilled Norwegian salmon paillard. When you make reservations, request a table overlooking the spectacular fountain. Jackets required; business casual for lunch. Prix fixe dinner $120, with flight of wines $150.

SOUTH PHILLY. One of many places billed as Philly's "Best," Geno's certainly has its fair share of devotees on the south side of town. Begun in 1966 by fella named Joe Vento, this 24/7, take-out-only joint has the art of serving cheesesteaks down to a science. That is to say, at the first window, order your sandwich. Without prompting, indicate American, provolone or Cheese Whiz and whether or not you want onions. Pay, pick up your order, and move down to the next window for a drink. And just in case you're curious, you really shouldn't leave town without trying the Cheese Whiz variety.
