The Uno Chicago Grill on Boylston Street in Boston, as well as retail properties in Cambridge recently changed hands in deals between $4.2 million and $4.9 million, says Boston commercial real estate firm Colliers International.

In a press release, Colliers said the deals come as the firm focuses on urban retail, "which we feel is underserved by most real estate investment advisors," the firm said.

The firm brokered the $4.9 million sale of 727-731 Boylston St. in Boston’s Back Bay to Linear Retail Properties LLC. The building is leased entirely to Uno Chicago Grill.

It also brokered the sale of 161-171 Huron Ave. in Cambridge. That property is 100 percent leased to a variety of tenants and sold for $4.2 million. RCG of Cambridge was the buyer.

Colliers said it also reached an agreement with a "regional firm" to buy 85 and 107 First St. in East Cambridge. That building is home to six retail tenants.
