Pub Tiki had "1-1/2" incorporated into its logo tiki -- the reason for this is unclear, it has been rumored that this was their promise to pour drinks on the heavy side (1-1/2 shot where 1 was called for), or perhaps it was a reference to their 1-1/2 hours of free parking. There were other restaurants in this "Pub" chain, but this was the only Polynesian themed location. A non-tiki Pub location still exists in New Jersey.
Pub Tiki closed in 1977 upon expiration of its lease. For the next 35 years, clothing store Knit Wit, now at 1729 Chestnut, occupied the space; it is now occupied by Intermix, a high end boutique chain based in Manhattan.
