If you're coming up 35E north of downtown up to 635 (crossing over to 75) you will hit what I consider the best stretch of AMP's in the country, from Market Center up to Royal Lane.
Market Center exit to the west: Jade
Inwood Exit to the west: N. Silver
Mockingbird Exit to the west: Dollhouse
Northwest Highway Exit to the west: Aloha/Cleopatra, Oceanside
Walnut Hill Exit to the east: 7th Heaven
Royal Lane Exit to the west: Smile, Blue Angel, about 6 or 7 others
And that doesn't include the two or three others that have opened recently or are about to open.
Keep in mind that L3 is the standard at all of these places, and that the price point for L1 and L3 is the same, no discount for lesser service.
