3.2 ABV is seriously under spec for the styles mentioned. 4-6% is typical for many craft brew styles, according to Beer Judging Certification Program guidelines.

Guys, calm down. First, 3.2 ABW is actually 4.0% ABV which is what most states use to designate the alcohol content of their beer.
Second, unless they want to pay the kickbacks to the distributors, thus making it much more difficult to sell at a profit, then 3.2 is all he can brew legally. The red tape to brew "strong" beer for a brewpub is a non-starter.
Third, shhhhhh. As long as he doesn't go crazy making big styles like doppelbocks and barleywines, then he can make really good "3.2" beer. Wink wink nod nod.
Why don't you give his beers a try and THEN criticize his Brewmaster ability. I'm quite certain he is aware of styles and knows what that means. If his beers suck, then throw all the tomatoes you want at him.

For most people, whether a beer "sucks" or not depends on whether they like it, and that's a fair and practical way to approach things. As you know, craft brewers also factor in how well a beer conforms to the BJCP standards of its style. A low-point IPA might appeal to restaurant goers, but it's not, strictly speaking, a great example of the style. It's like show dogs vs. the lovable family mutt. It all depends on what you're looking for, and obviously, this is a restaurant, not a brewing competition. The average diner will be just fine with the "craft beer" billing, but some of us beer snobs might cringe at the 3.2 restriction. I'll give Pi a try, though. The decor sounds cool, and if the pie is good and the ale OK, then that will work for me.

Micro low-point ABW/ABV is really starting to become a trend and an art in craft breweries. Many breweries, especially in the NW, are working hard to develop low ABV beers that retain "craft style" flavor. This past year Food & Wine magazine and Draft magazine both had articles on the matter.
I myself have only tried low-point craft brews at Bricktown Brewery with mixed reviews. I appreciate anyone who brews their own crafts but I know the brewmaster at Bricktown Brewery (now owned by Rock Bottom) aren't well know, but Vinnie Cilurzo of Russian River Brewing Company (Pliny Pliny Pliny!) is delving into low-point brews and recently admitted to only drinking low-point beer at home (that he brews) and at the RRB pub.
