Always had good service from Strada myself, OK it helps if you're fond of Italian road bikes to but not found them snobbish/unhelpful.
I normally end up in a foetal position after checking the price tags in Mud Dock but good for Trek/Scott.
Spesh Concept Store I really like but you've obviously got to have some affinity to Spesh gear.
Bike is OK, there's a high ratio of low-end stuff to high end stuff though (I guess they want to run a business rather than boutique 😉 ).
Terry's is about as close to what I'd call a traditional LBS near Bristol but it's a pretty small shop with limited range. Great for spares/advice but not really worth the journey if you just want to browse high end bikes.
