The La Mesa Chamber of Commerce will host a “business after hours” evening mixer from 5:30 to 7 p.m. on Thursday, June 6, at Cali Comfort, a barbecue restaurant and sports bar, at 8910 Troy St. in Spring Valley. Barbecued tri tip and pulled pork, along with beans and cobbler, and beer tastings will be provided by Cali Comfort, known for its pulled pork sandwiches, named one of the most popular in San Diego, according to several surveys. The mixer will include raffles, as well as attendance drawings sponsored by Business 2 Business Connection, Borrego Springs Bank, La Mesa Courier and Opus Bank. Admission is free to La Mesa Chamber members, $10 per person for guests. RSVP is requested before June 3 so that enough food can be prepared.
