High Bluff Capital Partners, a private equity firm in San Diego, recently made its second acquisition of a restaurant franchise in as many months.

The firm on July 9 announced it had acquired Taco Del Mar, a Washington state-based fast-casual chain, from Franchise Brands LLC.

Taco Del Mar, which has more than 100 locations in the U.S. and Canada, opened its first restaurant in Seattle in 1992.

In June, High Bluff acquired Denver-based QCE LLC, the parent company of toasted sub sandwich chain Quiznos.

Terms of the transactions were not disclosed.

“We see tremendous opportunity to continue to build out our platform in the mid-market restaurant franchise segment, which has many regionally strong concepts with significant growth potential,” Gerry Lopez, operating partner at High Bluff Capital, said in a July 9 news release.

The investment team at High Bluff, headed by founder Anand Gowda, has experience in the restaurant, entertainment, food, beverage and retail sectors. The firm focuses on making investments in consumer-facing companies.
