Just happened by GHP on its opening day on West Portal Ave. (#170, formerly West Portal Bakery). They are dishing out generous slices for $2 of many of their standard combinations and seem to have discounts on full sized pizzas. A small was a flat $13 which is at least a couple of dollars cheaper than their usual price--I can't remember the prices of the other sizes. They were taking cash only and sticking it into a cash drawer, and the line was out the door when I left. I haven't delved into my Special Combination and Hilda's Favorite slices, but I'm expecting the same solid pizza I remember eating from the Potrero Hill location growing up.
Having just moved back to the West Portal area I'm excited by the new eateries like Market & Rye and classics like GHP. I also saw a sign for a Greek restaurant called Orexi coming soon on the same block as the post office. Fingers crossed for another nearby delight.
