I come here mostly for craft beers. In that regard their selection is smallish and random. But that makes coming here kind of an adventure just to see what they have. If it were just for the beer selection I'd give them three stars. But they do have what appears to be a fairly expansive wine selection, and their staff seems knowledgeable about wines and booze. They also have a nice deli and cafe and it's all such a lovely little place to grab a gourmet sandwich to nibble on after you've picked up a couple bottles of trendy syrah, which they'll gladly open for you to serve on-premises with your meal. Same goes for any beer they carry, and they have a quick-chill cold-water tank that will chill your beer or white wine in a matter of minutes, ready to serve long before your meal arrives.
After they abandoned Monticello for greener pastures, I resisted the urge to patronize their new location for years. But I've come to appreciate that they just couldn't do what they've done in Champaign if they were still out in sleepy little Monticello. Still, I wish they would have kept their Monticello store as an outpost of civilization while still doing their thing in Champaign. That would make Sun Singer doubly cool.
