Sometimes regular expressions are the tool to do the job:

Given:

>>> input = [u'Espa\xf1ol', 'Health & Fitness Clubs (36)', 'Health Clubs & Gymnasiums (42)', 'Health Fitness Clubs', 'Name', 'Atlanta city guide', 'edit address', 'Tweet', 'PHYSICAL FITNESS CONSULTANTS & TRAINERS', 'HEALTH CLUBS & GYMNASIUMS', 'HEALTH CLUBS & GYMNASIUMS', 'www.custombuiltpt.com/', 'RACQUETBALL COURTS PRIVATE', 'www.lafitness.com', 'GYMNASIUMS', 'HEALTH & FITNESS CLUBS', 'www.lafitness.com', 'HEALTH & FITNESS CLUBS', 'www.lafitness.com', 'PERSONAL FITNESS TRAINERS', 'HEALTH CLUBS & GYMNASIUMS', 'EXERCISE & PHYSICAL FITNESS PROGRAMS', 'FITNESS CENTERS', 'HEALTH CLUBS & GYMNASIUMS', 'HEALTH CLUBS & GYMNASIUMS', 'PERSONAL FITNESS TRAINERS', '5', '4', '3', '2', '1', 'Yellow Pages', 'About Us', 'Contact Us', 'Support', 'Terms of Use', 'Privacy Policy', 'Advertise With Us', 'Add/Update Listing', 'Business Profile Login', 'F.A.Q.']

Then:

>>> pattern = re.compile(r"^[A-Z\s&]+$")
>>> output = [x for x in list if pattern.match(x)]
>>> output
['PHYSICAL FITNESS CONSULTANTS & TRAINERS', 'HEALTH CLUBS & GYMNASIUMS',
'HEALTH CLUBS & GYMNASIUMS', 'RACQUETBALL COURTS PRIVATE', 'GYMNASIUMS',
'HEALTH & FITNESS CLUBS', 'HEALTH & FITNESS CLUBS', 'PERSONAL FITNESS
TRAINERS', 'HEALTH CLUBS & GYMNASIUMS', 'EXERCISE & PHYSICAL FITNESS
PROGRAMS', 'FITNESS CENTERS', 'HEALTH CLUBS & GYMNASIUMS', 'HEALTH CLUBS
& GYMNASIUMS', 'PERSONAL FITNESS TRAINERS']
