This just in: Chef William Kovel’s “Catalyst”:http://boston.menupages.com/restaurants/catalyst/, which we touted in our “fall-preview slideshow”:http://boston.www.grubstreet.com/2011/08/fall-restaurant-preview-slideshow.html, will open in Kendall Square this evening. It was slated to open over the weekend, but apparently there were some delays involving their liquor license. However, per their Facebook page, everything has been resolved and the big day is here at last. Yum yum! [“Facebook”:https://www.facebook.com/CatalystRestaurant]
