Just stopped by and chatted with the people opening up Platanos, a Latin-fusion place in the old Mereb location. They said they are opening this Tuesday or Wednesday. Chef used to be at Rotunda and Aqua. Nothing over $15, but it's clearly going to be upscale. Sounds like it's in the category of nearby Alma (22nd & Guerrero) and Limon (17th & Mission), both favorites of mine.
