For those of us cooped up in an office all day, it's nice to escape outside at midday or after work and get a drink or a bite to eat. After last week's heat wave, downtown was full of happy people basking in the sunshine and eating meals outside. Now, there's another place joining the throng. Starting May 1, RA Sushi will provide outdoor seating with about 35 tables with umbrellas along Lancaster Street. See you there.
