McGuffie's Live is a dedicated live music venue in San Carlos at 8515 Navajo Rd, San Diego, 92119, operating out of the space formerly occupied by Navajo Live and Second Wind. The venue opened in 2025 with a renovated stage, upgraded sound system, and a booking calendar that programs original bands and tribute acts Thursday through Sunday. Monday nights run a recurring blues jam that draws sit-in players from across San Diego, Wednesday is karaoke with a full-catalog digital system, and the first Tuesday of each month hosts an open-mic showcase for unsigned artists. Navajo Road runs through the commercial core of San Carlos, less than a mile from the Cowles Mountain trailhead at Barker Way, and the strip-mall corridor shares a parking lot with Mountain Mike's Pizza, where families picking up takeout hear the sound check through the wall. The bar carries a full liquor license and pours from a rotating local craft tap list that leans toward San Diego IPAs and pale ales. The room holds roughly 100 standing capacity with a low stage that puts performers at eye level, a format that favors blues, rock, and acoustic acts over high-production electronic sets. Free parking fills the lot in front of the venue, and the Lake Murray residential neighborhoods to the south feed a walkable audience on weekend nights. Morning-after regulars from the Saturday night lineup cross Navajo Road for drip coffee at Cowles Mountain Coffee before heading to the trailhead. The PA system pushes a 2,000-watt main stack with monitor wedges on stage, and the house sound engineer mixes front-of-house for every booked act.
