The Subway chain restaurant at 2216 Wisconsin Ave is expected to close. The space is up for lease and advertised as 2,400 square feet of retail space with a "negotiable" price. Limited foot traffic at the southern end of the strip next to Mad Fox Tap Room and a somewhat small lunch crowd may have contributed to the decision. Subway has tried to entice more customers with coupon mailings recently. Rents are high on Wisconsin Avenue in Glover Park, and restaurants find it challenging to succeed without liquor sales.
