For the business entities, their contact details, opening hours, 
pricing, payment options, and business functions, I strongly recommend 
GoodRelations,

http://purl.org/goodrelations/

GoodRelations should cover most of your needs out of the box for any 
type of business or service offering on the Web, including price ranges 
etc.  Also, GoodRelations is a stable and mature ontology project with 
sustained support from numerous players. It is designed to work in pure 
RDF/LOD scenarios as well as in controlled OWL DL projects.

The ontology primer is available at

http://www.heppnetz.de/projects/goodrelations/primer/

A tool for creating basic descriptions for any business is at

http://www.ebusiness-unibw.org/tools/goodrelations-annotator/

You can also use that tool for learning the recommended GoodRelations 
modeling patterns. The tool only allows chosing from the first two 
hierarchies of eClassOWL, but you could replace the class IDs in the 
RDF/XML later on in order to make the description more specific.

A restaurant could use the eClassOWL 5.1.4 category 2520 (Food and 
services) or one of the following more specific classes:

25-20-01-00 -  Restaurant (service), [ eclass:C_AKG508003-gen ]
25-20-01-01 -  Restaurant with conventional service (service),  [ 
eclass:C_AKG509003-gen ]
25-20-01-02 -  Restaurant with self-service (service), [ 
eclass:C_AKG510003-gen ]
25-20-01-03 -  Cafe (service),   25-20-01-03 [ eclass:C_AKG511003-gen ]
25-20-02-01 -  Bar (service), [ eclass:C_AKG515003-gen ]
25-20-02-02 -  Bar and entertainment restaurant (service) [ 
eclass:C_AKG516003-gen ]
25-20-02-03 - Disco and dance restaurant (service)  [ 
eclass:C_AKG517003-gen ]

The proper gr:BusinessFunction would be gr:ProvideService, since eClass 
classifies restaurants as types of services. (When using an ontology 
that defines particular types of meals, then the proper business 
function would be "sell".)

A hotel could use the eClassOWL 5.1.4 category 2512 (Travel Management) 
or, better, one of the following more specific classes:

25-12-13-01 -  Hotel (travel management),  [ eclass:C_AKG314003-gen ]
25-12-13-02 -  Hotel garni (travel management),    [ 
eclass:C_AKG315003-gen ]
25-12-13-03 -  Inn (travel management),[ eclass:C_AKG316003-gen ]
25-12-13-04 -  Pension (travel management),  [ eclass:C_AKG317003-gen ]

The proper gr:BusinessFunction would be gr:ProvideService, too.

eclass: = http://www.ebusiness-unibw.org/ontologies/eclass/5.1.4/#

Note that GoodRelations can be also used without eClassOWL or with any 
other ontology for describing WHAT is being offered. You can also use 
dbPedia URIs or other domain ontologies.

Best
