ISO Venue for Cocktail Party/Reception for 150+ near convention center
The trick is that it cannot be a hotel ballroom or at the convention center (rooftops are okay, but nothing at the Marriott or Loews), cannot be a chain restaurant, and must be within walking distance (around 1/2 mile max) from the Marriott.
Restaurant or bar buyouts tend to work well, but other interesting venues that I can bring in a caterer are also great. Really looking for a place that you would want to go to, even if you weren't just in the area for a convention.
Was interested in The Franklin, even though it's on the far side of my walking-distance limit, until I saw that they can only accommodate 60.
Locals, what would you suggest?
National Constitution Center?
There are other potentially wonderful venues for an event like this in Philly (Art Museum, Barnes, Kimmel, College of Physicians), none within walking distance unfortunately
Penn owns a private club called the Mask and Wig. Its great for private parties, (and any Penn alums may remember it) It is 6 tenths of a mile according to Google Maps. They have a full bar there, and a catering company that can arrange food. Truly a great location. Max accommodation is 200.
I know the Barnes Museum is now available for private functions, especially in the evening. Again a bit further than you wish to travel.
You might want to consider Valanni. Perfect for a cocktail party. I know they do packages. Not a big place, but they may be able to work with 150. I think it's Spruce and 12th, so definitely within walking.
