This week we checked in on the dining scene at Westfield Montgomery mall, where Urban Plates and Poke Papa are now under construction in the former Naples space. But what’s up with Viva Japanese Steakhouse, which was supposed to have opened months ago across from the ArcLight Cinema? A peek through the windows reveals that little progress has been made since last summer, and the restaurant’s owner has not returned our messages. The mall says Viva will open around Christmas, but we have our doubts. Moving along to the other side of the Dining Terrace: A 7-11 (of all things) will be opening next to Chick-fil-A, and the gourmet popsicle shop we told you about last month is changing its name from Pop Culture to Frozen Stuff on a Stick. That one should be open in a few weeks.
