51 Lincoln has filed for Chapter 11 bankruptcy protection, Boston.com is reporting. The filing comes a week after Fournier closed his other restaurant Waban Kitchen.

[Chef-owner, Jeff Fournier] cited an explosion of new restaurants in the Boston area and an influx of costs and expenses to running a small restaurant as reasons for the restaurant’s financial distress. He added he has no intention of closing or selling the nine-year-old upscale dining spot, which has made numerous appearances in various “Boston’s Best” lists by The Boston Globe, Boston magazine, and Improper Bostonian over the years..

Thanks to Steven Feinstein for calling this to our attention via the Newton Highlands list serve.
