PB....as usual I have a few suggestions!!! First, since you've already tried the IPA and enjoyed it; try each of the other IPAs at the Leaf &Ale!! Now I'm going to list most of the breweries with which I'm familiar. Each time you visit the L&A, pick up a bottle from say, five or six, of them and keep a log/diary of which ones you like and/or dislike. Many of my favs come from one of these:
Anchor Steam, Avery, Bar Harbor, Bass, Becks, Calhouns, Duck-Rabbit (one of my wife's favorites!), Fort Collins, Flying Dog, Guinness, Hacker-Schorr, Left Hand (big fav of mine), Lost Coast, North Coast, Pilsner Urquell, Redhook, Sam Adams, Sammy Smith (IPA and Oatmeal Stout are awesome), Shipyard, Sierra Nevada, St. Pauli Girl, St. Peters, Smithwicks (pronounced Smith icks, no "w"), Warsteiner, and Yuengling.
Within each of these (other than the single brews like Bass or Becks), you'll find a range of lighter lagers to hoppier IPAs, different ales, and even a few fruit-based brews! Enjoy and have fun!!
