You do know that next week is race week? The Island is going to be nuts beginning sunday when the first ones start arriving, and get progressively crazier each day, probably hitting it's peak on Tuesday or Wednesday depending on if it's a fast race or not.
I referee vintage base ball tournaments on the Island at the grand hotel....there is actually a store on the Island that sells Michigan Craft beers, and you can iirc do mixed sixers. It's the Michigan Peddler at Main Street Center. It's a little pricy though.
If you're staying in St. Ignace, Doud's Market also has an OK beer selection of Michigan Beers. 699 W. US-2 St. Ignace, MI 49781
The Doud's on the Island itself might have some too, but I can't recall. I stay in St. Ignace, and bought my beer at Doud's.
Most of the bars in St Ignace has some form of Michgan Beer either on tap or in bottles....I found Bell's in a couple places, but most of the joints had 1 or 2 from Cheboygan Brewing Company
or IIRC Saugatuck
out of Douglas.
There's not a heck of a lot up there, but it's not a vast wasteland of BMC either. You WILL find stuff...but brew pubs, no...Michigan Beer even in the crappiest of places? Yes.
If you're looking for food and are hitting St Ignace at all, be sure to hit up the establishments owned by Joe Durm a local institution there's three places, and they are all funky and the food is good.
My favorite, and where I ate breakfast all the time when I was up there last summer was Java Joe's Cafe
Some of the best breakfasts I've ever eaten....
He also has a really good Mexican Place Cantina Joe's
, really good food, really good margaritas and Cheboygan beer on tap.
He used to have a hot dog stand that served all regional style of hotdogs, but it looks like this year he opened a health food restaraunt out of it instead called the Garden
You can't miss his places, they are all brightly colored.
