Why are you dining alone? If it's because you have a personality most often described as "morose," the Sports Exchange is just the place to cheer you up. OK, who are we kidding? Let's just say this is the sort of place that might make you less morose. Maybe you're dining out by yourself because you meant to have dinner at home while watching the Marlins, but your TV set is on the blink. If that's the case, there are 27 high-def plasma screens posted around the room, including what is billed as the largest screen in town (there is also a 16-foot ticker with stock updates, but we're assuming you're not that much of a geek). Maybe you're out and about because you were feeling a bit cramped in your apartment. The Exchange touts the longest bar in the Gables — 50 feet, as in plenty of room to stretch out. And yes, there are brews galore — Guinness, Yeungling, and Shock Top on tap for $4 apiece; the same price nets a bottled import. Dining alone because you're cheap? Then come here from 5 to 8 p.m. and enjoy two-for-one well drinks and half-off appetizers. There are late-night food and drink deals too. Then again, maybe you enjoy the company of countless friends and dine solo because you simply relish doing so — and doing so at the Sports Exchange for all of the aforementioned reasons. Plus there's one other reason: The fare is finer than typical pub grub, and unless you're gonna go with the baby-back ribs, just about everything is under $20 — wood-oven pizzas, burgers, sliders, Buffalo wings, and delectable mini hot dogs in brioche buns topped with chili, onions, and cheddar cheese. Of course, if you make a habit of eating those, you'll probably be dining alone for some time to come.
