Hi,
In what was once a repair garage in front Il Mulino - Maria's Bakery, the Once Upon a Bagel family of restaurants has opened The Mean Wiener. Actually this is their second business concept at this location, last summer they opened "Catering by Once Upon." A narrative on The Mean Wiener's take-out menu offers an explanation:
To our friends ...
With the closing of "Catering by Once Upon" due to a weak economy, we were left with a fully equipped facility in a beautiful building in a great community.
A decision was made to create a special eatery for friends, neighbors and visitors.
Our goal is to satisfy your tastebuds in an atmosphere that is fun, friendly and fast.
We will serve you in a manner that will make you want to return and bring your friends with you.
Thank you!

I had walked in once to "Catering By Once Upon," to find it was selling food available to take home to reheat. Some of the sleepiness I sensed may have been a business that wasn't taking off as hoped. Their reworking the concept to ride out the tide during this period is quite reasonable.
I stopped by Mean Wiener for lunch today. I ordered their signature, "The Mean Wiener," a foot long 100% Black Angus Sirloin 1/2 pound hot dog with Chicago style fixings. There were options to have it with cheese, with chili or chili and cheese.

The hot dog was quite flavorful, though no snap. If this hot dog was simmered, it didn't seem like it. It was either cooked on a griddle or on those rollers you see in gas stations. The kitchen is enclosed, thus any visual hints on its preparation were not available.
The condiments need some tweaking. What appears to be large sport pepper in the middle is really a pickle half. For a foot long hot dog, I would have hoped for at least two pickle spears. Instead of tomato wedges, there were chopped tomatoes. The onions were not chopped, instead they were tattered onion bits similar to onions over-processed in a food processor. Most of the condiments were in the middle, I redistributed them to the edges before eating.

The onion rings were pretty good with real onion inside with a light, crispy batter. I didn't try their fries, which they menu advises are fresh cut.

The Mean Wiener is still finding its footing. They have dropped the price of buffalo wings, which were pretty high. In their take out menu, 18 pieces were priced at $16.99. I recall from their in-house signage, you could get 50 pieces for approximately $29.99. Wednesday is 50 cent wings or 50 pieces for $25.
They offer a homemade tamale with or without chili. It is quite reasonable to create your own Mother-in-Law once you explain what you want.
